haha funny you say that, he is in my space at uni, and i received a phone call thismorning from a friend who said he was dead.
i quickly went in to investigate, and it turns out he was just chilling at the bottom of the tank, still alive and well. but just not moving.
gave him some food and quickly sprouted back to life.
and no i wont show him a mirror hahaha, he is placid and i dont want him to die just yet
